Mr. Dupuis doesn't think much about it. He's sure that there's still a place for him in Su's heart. He tells his son that he's going to go back to school, and that's fine. He just wants to make sure that he eats more at home and that he has a good night's sleep. He says he'll go to bed and wake him up if he needs anything. He wants to go to school so that he can make a better life for himself and his family.
